Vacuum System is generally adopted when the extraction distance is less, numbers of ESP hoppers are more and plant layout demands two-stage conveying. Vacuum System includes conveying of fly ash from various fly ash hoppers up to the intermediate / buffer / surge hopper (ISH) located near ESP.


A thermal power station is a power station in which heat energy is converted to electric power.In most of the places in the world the turbine is steam-driven.Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.


Pressurized pneumatic ash conveying may also be employed. Coarse ash material such as bottom ash is most often crushed in clinker grinders (crushers) prior to being transported in the ash conveyor system. Very finely sized fly ash often accounts for the major portion of the material conveyed in an ash handling system.
